The object of this invention is to furnish an improved machine for putting out or dressing sheep-skins, goat-skins, and other similar skins, which shall be so constructed as to force out the water and stretch the skins, causing them to dry in much less time than when put out by hand, and rendering it unnecessary to nail the skins to boards to stretch and drythem, thus greatly economizing time, labor, and room.

The invention consists in the combination of the sliding bed-plate, the vertical table or ta bles, and the four wheels or sets of radial arms, providedwith rollers,brushes, and slickers, with each other and with the ways, the shafts, and'the frame, in the combination of the forked upper arms, the rods, and the lower arms with the hubs of the wheels or arms, the frame, and the swells formed upon'the bedplate of the vertical tables in the combination of the rubber or other springs with the ad justable supports for the armed rods and with the adjustable supports for the friction-rollers connected with the lower'arnis of said armed rods; in the combination of the springs with the shafts and the four wheels; in the combination of the bands or equivalent connectingrods and wheels, and the pulleys and shaft with the wheel-nuts of the adjustable supports for the armed rods, in the combination of the racks, the gear-wheels, and the double clutch with the bed-plate of the vertical tables; in the combination of the clutch-lever, the sliding bar, the U-lever, and the catchbars with the double clutch and the frame; in the combination of the toe andthe adjustable stop-pins with the clutch-lever and with the bed-plates provided with the series of holes; in the combination of the grooved wheels, the brushes, and the pivoted U bars or frames with the frame of the machine and the sliding vertical tables 5 in the combination of the rack, the gear-wheel, and the bands with the bedplate of thevertical tables andwith the grooved wheels, and in the combination of the gearwheels, the stationary gear-wheels, and the holding-bar with the shafts and the rollers of the wheels or arms, as hereinafter fully described.

A represents a pair of sills or bars, to the sides or tops of which are attached slides B, upon which a bed-plate, 0, moves back and forth. To the bed-plate 0, near one or both ends, are attached one or two tables, D. upon which the skins are spread to be dressed. To the under side of the bed-plate 0, near its side edges, are attached racks E, which racks should be alike when two tables are used; but when only one tableis used, one of saidracks or gears may be made larger than the other, to cause the table D to move faster in one direction than in the other. The teeth of one of the racks E mesh into the teeth of a gear-wheel, G, that -rims loose upon the driving-shaft F. The teeth of the other rack E mesh into the-teeth of a gearwheel, H, attached to a shaft, I, which is pivoted to the side A. With the gear-wheel H is rigidly connected a gear-wheel, J, the teeth Around the center of the double clutch is formed a ring-groove to receive the forked end of the lever M, which is pivoted to a support between the sills A, and passes between two pins attached to a bar, N. The bar N passes through and slides longitudinally in holes in the sills A, and to its end is pivoted one of the arms of the lever O, the middle part of which works in bearing attached to the floor or other support at the side of the machine, The arms of the lever 0 project upward at the end parts of the side of the-machine, andmove along catch -bars P attached to the frame Q of the said machine, and by which the said lever is held in any position into which it may be adjusted.

To the end of the driving-shaftG are attached a fast pulley, R, and a loose pulley, S, to receive the driving-belt, and to the said shaft is also attached a pulley, T, to receive a band, U, which also passes around a pulley, V, attached to the shaft W.

The shaft W revolves in bearings at one end of the top of the frame Q, and to it, or to the pulley V, is attached a bevel-gear wheel, X, the teeth of which mesh into the teeth of a bevel-gear wheel, Y, attached to the end of i the shaft Z.

which mesh into. the teeth of a bevelgear wheel, B attached to the shaft 0.

The shaft 0 is placed parallel with the shaft W, and revolves in bearings at the other end of the top of said frame. The shafts W 0 thus revolve in opposite directions and toward each other, and upon each of them, between the sidebars of the frame Q, are placed two wheels or series of radial arms, D. The arms of the wheels D are provided with rollers d brushes (l and glass and rubber slickers d. The brushes d are made with their forward edges serrated, and beveled upon the rear side. This construction diminishes the friction as the forward edges of said brushes strike the skins, and the bevels carry off the dirt taken from the skins, so that it cannot clog the machine or impede its working.

The wheels D of each pair are held apart or outward by spiral springs E placed upon the shafts W 0, between the said wheels D and a collar formed upon the middle parts of' the said shafts W 0 The outer ends of the hubs of the wheels D have ringgrooves formed around them to receive the forked upper ends of the arms. F,

to its end, and having a rubberor other spring, M, placed upon it to give it the necessary yield. r

. The friction-wheels L bear against the edge of the bedplate 0 of the table D, or against a flange or rib formed upon said bed-plate, which edge, flange, or rib is made with swells 0 in such positions as to force the arms J outward, when the tables D have fully entered the machine to force the wheels D against the sides of said tables D with the necessary force to produce the proper effect upon the skins, and to allow said wheels to be forced outward by the springs E when the tables are moving outward.

The nuts h of the bolts H are made as pulleys to receive a band, N, so that the two nuts 71/ upon each side of the machine may be turned together, and one of the nuts h" upon each side is made double to receive a second band, 0.

The two bands 0 also pass around pulleys P attached to the opposite ends of a short shaft, Q, which passes through and works in bearings in the sills A, so that all four of the nuts h may be turned to the same extent by turning one of them. The four nuts h" may be connected by gear-wheels and rods, if desired.

To the upper side of the bed-plate O of the tables D is attached a'rack, It, into the teeth of which mesh a small gear-wheel, S, pivoted to theframe Q, and with which is rigidly connected a double pulley, T, around which pass two bands, U.

The bands U also pass around pulleys V attached to the short shafts W, which are pivoted to the bars orjframes 00 near their outer parts or bends, and to the middle parts of which are attached groovedwheels y, to bear upon the upper edges of .the tables D, to smooth out, stretch, and press the mid- .dle part of the skins.

To the bends of the bars or frames w are attached brushes 2, to operate upon the part of the skins passing over the upper edges of the tables D.

The arms of the bars a are pivoted to the frame Q, and their ends extend inward, and

have inwardly-projecting lugs formed upon them to receive the set-screws X, the forward ends of which rest against the under sides of the top bars of the frame Q, to enable the wheels Y to be adjusted to. bear with any desired force upon the upper edges, of'the tables D.

The outer parts of the bars on are held downward, holding the wheels Y down upon the tables D by springs ar attachedto the said bars and to the frame g It will be observed that the direction of motion of the wheels Y will be changed as the direction of motion of the tables'D and bed-plates O are changed. The movement of the bed-plate C and tables D may be stopped automatically at any desired point, when moving in either direction, by pins 0 inserted in one or another hole of the series of holes 6, ormed in the middle and end parts of said bed-plate, or in a bar attached to the end of the bed-plate, as shown in Fig. 4, which pins strike a toe, m, formed upon the clutch-lever M, and thus throw said clutch out of gear.

The rollers d of the wheels or arms D have small gear-wheels A attached to their inner ends, the teeth of which mesh into the teeth of stationary gear-wheels B attached to the lower ends of the bars or beams 0 and through which wheels and bars the shafts WC pass.

- The upper ends of the bars or beams O are atthe rods G, and the arms J with the hubs of the wheels or arms D, the frame Q, and the swells 0 formed upon the bed-plate Gof the vertical tables D, substantially as herein. shown and described.

3. The combination of the rubber or other springs I M with the adjustable supports H for thearmed rods F G J, and with'the adjustable supports K for the friction-rollers L, connected with the lower arms J of said armed rods F G J, substantially as herein shown and described.
